Abstract

The present invention provides a motor capable of efficiently electrically connecting a ground terminal to a stator core. In the motor (1), a power feeding portion (8) is provided on the outer peripheral side of a metallic iron core holder (4) holding the stator core (5) inside. A power terminal (87) electrically connected to the stator coil (6) through a wiring member (86) and a ground terminal (88) are held by a metal terminal holder (80) in the power supply unit (8). The ground terminal (88) is electrically connected to the terminal holder (80), and the terminal holder (80) is fixed to the iron core holder (4) in contact with the iron core holder (4). Accordingly, the ground terminal (88) is electrically connected to the stator core (5) through the terminal holder (80) and the iron core holder (4).

Description

technical field [0001] The present invention relates to a motor provided with a power supply unit on the outer peripheral side of a stator. Background technique [0002] In the motor, as a structure for supplying electric power to the stator coil wound on the salient pole of the stator core, a connector member is attached to the outer peripheral side of the stator, and the stator coil is held on the connector member. The structure of the power supply terminal connection. In this case, one end of a wiring member such as a wire is connected to the ground terminal held by the connector member, and the other end of the wiring member is connected to the stator core by bolts or the like (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 11-289702 [0004] However, in the structure in which the ground terminal held by the connector member is connected to the stator core through a wiring member such as a wire, as in the structure describ...
